Description:

Background Antimicrobial resistance (AMR) is an urgent global crisis and one of the world's most complex challenges. Although there is increasing evidence of its impact on human mortality and morbidity, precise burden estimation has many challenges, and thus far has been elusive for the Eastern Mediterranean Region. Here, we present a comprehensive time-trend analysis of regional and country-level AMR burden estimates in the WHO Eastern Mediterranean Region (EMR), between 1990 and 2021, with forecasts up to 2050. Methods We estimated deaths and disability-adjusted life-years (DALYs) attributable to and associated with AMR for 11 infectious syndromes, 22 bacterial pathogens, and 84 pathogen–drug combinations for the WHO EMR and each of its countries from 1990 to 2021. Data were obtained from mortality registries, surveillance systems, hospital records, systematic literature reviews, and other sources. We based our modelling approach on five broad components: the number of deaths in which infection had a role, the proportion of infectious deaths attributable to a given infectious syndrome, the proportion of infectious syndrome deaths attributable to a given pathogen, the percentage of a given pathogen resistant to an antimicrobial drug of interest, and the excess risk of mortality (or duration of an infection) associated with this resistance. These components were then used to estimate the disease burden by using two counterfactual scenarios: deaths and DALYs attributable to AMR (considering an alternative scenario where drug-resistant infections are replaced with susceptible infections), and deaths and DALYs associated with AMR (considering an alternative scenario where infections would not occur at all). Predictive statistical modelling was applied to generate estimates of AMR burden for each country. We also generated AMR burden forecasts up to 2050. We generated 95% uncertainty intervals (UIs) for the final estimates by taking the 2·5th and 97·5th percentiles across 500 draws through the multistage computational pipeline, and models were cross-validated for out-of-sample predictive validity. Findings We estimated 380 000 deaths (95% UI 332 000–426 000) associated with bacterial AMR and 92 800 deaths (78 300–111 000) attributable to bacterial AMR in the EMR in 2021. In the past 31 years, there was considerable variation in AMR mortality trends across countries of the region and different age groups. Between 1990 and 2021, associated deaths among children younger than 5 years decreased by 50·0% (38·2–62·0), while those among adults aged 70 and older rose by over 85·7% (95% UI 57·0–115·7). Six pathogens were identified as the primary generators of burden: Streptococcus pneumoniae, Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, Acinetobacter baumannii , and Pseudomonas aeruginosa . A substantial increase in the AMR burden due to S aureus was observed between 1990 (28 200 deaths [21 600–34 000]) and 2021 (49 500 deaths [43 100–56 200]); consequently, in 2021, methicillin-resistant S aureus was a leading pathogen–drug combination for most countries in the region for deaths and DALYs attributable to, and associated with AMR. Somalia had the highest age-standardised mortality rates in the region: for deaths attributable to and associated with AMR per 100 000 population in both 1990 and 2021; conversely, the country with the lowest burden in the EMR was Qatar. By 2050, the number of deaths attributable to AMR in region is forecasted to reach 187 000 (157 000–223 000) and deaths associated with AMR were projected to reach 752 000 (629 000–879 000). Interpretation Our study shows that bacterial AMR has been a serious public health threat in the EMR for more than 30 years, with a substantial fatal and non-fatal burden for priority bacterial pathogens and pathogen–drug combinations. The magnitude of this issue, future projects, and the inadequate response capacity in many countries underscore the need for more stringent regional leadership in this field. The insights gained from this study can direct targeted mitigation strategies for individual countries within the region, aiding in resource allocation and funding decisions, and emphasising the need for collaborative multisectoral endeavours among nations to address this issue.

Description:

Background: Since its inception in 1974, the Essential Programme on Immunization (EPI) has achieved remarkable success, averting the deaths of an estimated 154 million children worldwide through routine childhood vaccination. However, more recent decades have seen persistent coverage inequities and stagnating progress, which have been further amplified by the COVID-19 pandemic. In 2019, WHO set ambitious goals for improving vaccine coverage globally through the Immunization Agenda 2030 (IA2030). Now halfway through the decade, understanding past and recent coverage trends can help inform and reorient strategies for approaching these aims in the next 5 years. Methods: Based on the Global Burden of Diseases, Injuries, and Risk Factors Study 2023, this study provides updated global, regional, and national estimates of routine childhood vaccine coverage from 1980 to 2023 for 204 countries and territories for 11 vaccine-dose combinations recommended by WHO for all children globally. Employing advanced modelling techniques, this analysis accounts for data biases and heterogeneity and integrates new methodologies to model vaccine scale-up and COVID-19 pandemic-related disruptions. To contextualise historic coverage trends and gains still needed to achieve the IA2030 coverage targets, we supplement these results with several secondary analyses: (1) we assess the effect of the COVID-19 pandemic on vaccine coverage; (2) we forecast coverage of select life-course vaccines up to 2030; and (3) we analyse progress needed to reduce the number of zero-dose children by half between 2023 and 2030. Findings: Overall, global coverage for the original EPI vaccines against diphtheria, tetanus, and pertussis (first dose [DTP1] and third dose [DTP3]), measles (MCV1), polio (Pol3), and tuberculosis (BCG) nearly doubled from 1980 to 2023. However, this long-term trend masks recent challenges. Coverage gains slowed between 2010 and 2019 in many countries and territories, including declines in 21 of 36 high-income countries and territories for at least one of these vaccine doses (excluding BCG, which has been removed from routine immunisation schedules in some countries and territories). The COVID-19 pandemic exacerbated these challenges, with global rates for these vaccines declining sharply since 2020, and still not returning to pre-COVID-19 pandemic levels as of 2023. Coverage for newer vaccines developed and introduced in more recent years, such as immunisations against pneumococcal disease (PCV3) and rotavirus (complete series; RotaC) and a second dose of the measles vaccine (MCV2), saw continued increases globally during the COVID-19 pandemic due to ongoing introductions and scale-ups, but at slower rates than expected in the absence of the pandemic. Forecasts to 2030 for DTP3, PCV3, and MCV2 suggest that only DTP3 would reach the IA2030 target of 90% global coverage, and only under an optimistic scenario. The number of zero-dose children, proxied as children younger than 1 year who do not receive DTP1, decreased by 74·9% (95% uncertainty interval 72·1–77·3) globally between 1980 and 2019, with most of those declines reached during the 1980s and the 2000s. After 2019, counts of zero-dose children rose to a COVID 19-era peak of 18·6 million (17·6–20·0) in 2021. Most zero-dose children remain concentrated in conflict-affected regions and those with various constraints on resources available to put towards vaccination services, particularly sub-Saharan Africa. As of 2023, more than 50% of the 15·7 million (14·6–17·0) global zero-dose children resided in just eight countries (Nigeria, India, Democratic Republic of the Congo, Ethiopia, Somalia, Sudan, Indonesia, and Brazil), emphasising persistent inequities. Interpretation: Our estimates of current vaccine coverage and forecasts to 2030 suggest that achieving IA2030 targets, such as halving zero-dose children compared with 2019 levels and reaching 90% global coverage for life-course vaccines DTP3, PCV3, and MCV2, will require accelerated progress. Substantial increases in coverage are necessary in many countries and territories, with those in sub-Saharan Africa and south Asia facing the greatest challenges. Recent declines will need to be reversed to restore previous coverage levels in Latin America and the Caribbean, especially for DTP1, DTP3, and Pol3. These findings underscore the crucial need for targeted, equitable immunisation strategies. Strengthening primary health-care systems, addressing vaccine misinformation and hesitancy, and adapting to local contexts are essential to advancing coverage. COVID-19 pandemic recovery efforts, such as WHO's Big Catch-Up, as well as efforts to bolster routine services must prioritise reaching marginalised populations and target subnational geographies to regain lost ground and achieve global immunisation goals.
